PFO closure and brain microemboli study
Part of Brain & nervous system, Genetic & congenital, Heart & circulation clinical trials.
This trial looks at whether closing a small hole in the heart (PFO) can reduce tiny clots traveling to the brain. It includes people who have had a stroke or migraine, and also those without symptoms but with high-risk features.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You have a PFO (hole in the heart) that lets through a moderate or large number of bubbles on an ultrasound test.
- You have had a stroke or mini-stroke in the last 6 months, or migraines for more than 1 year, with no other clear cause.
- If you have no symptoms, you must have a PFO with high-risk features (like doing frequent Valsalva maneuvers or having a certain heart anatomy).

This trial tests a new stitch system to close a small hole in the heart called PFO, which can cause strokes. It is for people who have had a stroke or mini-stroke linked to this hole.
This study looks at the detailed flow pattern through a patent foramen ovale (PFO)—a small opening in the heart—and how it may relate to stroke, TIA, or migraine. Doctors use special ultrasound testing with contrast to better understand who is most affected.
This trial studies whether a Cera™ device is safe and effective for closing a patent foramen ovale (PFO), a small hole in the heart. It is for adults whose PFO is linked to certain types of stroke or ongoing clot-related events.
This trial looks at the safety and results of closing a PFO (a small hole in the heart) in people who have had a stroke or embolism with no other clear cause. If you qualify, doctors will close your PFO using a small tube inserted through a blood vessel and then follow your health over time.
This trial tests a new device to close a PFO (a small hole in the heart) in people who have had a stroke caused by a blood clot passing through that hole. The goal is to see if the device can prevent another stroke.
This trial tests a new device to close a PFO (a small hole between the upper chambers of the heart) in people who have had a stroke caused by a blood clot. The goal is to prevent future strokes by blocking the hole.
